MODEM-BD (Modem Pool Circuit
Pack)
Refer to XXX-BD (Common Port Circuit Pack) Maintenance documentation for
circuit pack level errors. See also MODEM-PT (Modem Pool Port) Maintenance
documentation for related port information.
MODEM-PT (Modem Pool Port)
The Modem Pool Port provides an interface for digital and analog data
communication devices or ports connected to the PBX. It may be thought of as a
PBX data communications “conversion resource” because it converts analog
modem signals typically used in the telephone network into digital signals that are
compatible with the internal PBX network and vice versa.
There may be a number of these conversion resources available in the PBX, each
assigned to one of five available Modem Pool Groups. Only one conversion
resource is used per data connection. The PBX software usually adds the
conversion resource into a data connection if it determines that it is necessary for
the call. Typical connections that include Modem Pool conversion resources
include data calls from Analog Line or Central Office Trunk ports to any digital port
or Digital Line or Trunk ports to any analog port. An example of a Data Module to
Central Office Trunk connection using a Modem Pool conversion resource is
shown in
Figure 10-69 on page 10-1098 . When a local data call originates from an
analog port normally used for voice service only and terminates on a digital port, a
Data Origination access code must be dialed before the extension number for the
Modem Pool conversion resource to be included in the connection.
